INTRODUCTION: The prognostic value of peak VO2 and VE/VCO2 slope measured during cardiopulmonary exercise (CPX) testing has been well established in patients with advanced heart failure, but blood pressure response to exercise is less well characterized. METHODS: We retrospectively studied 151 outpatients who underwent CPX testing as part of an advanced heart failure (HF) evaluation. The outcome of interest was failure of medical management, defined by death, cardiac transplantation, or left ventricular assist device placement...

BACKGROUND: Conditions of excess androgen in women, such as polycystic ovary syndrome (PCOS), often exhibit intergenerational transmission. One way in which the risk for PCOS may be increased in daughters of affected women is through exposure to elevated androgens in utero. Hyperandrogenemic conditions have serious health consequences, including increased risk for hypertension and cardiovascular disease. Recently, gut dysbiosis has been found to induce hypertension in rats, such that blood pressure can be normalized through fecal microbial transplant...

Stromal cell-derived factor 1-alpha (SDF) is a potent bone marrow chemokine capable of recruiting circulating progenitor populations to injured tissue. SDF has known angiogenic capabilities, but bone marrow-derived cellular contributions to tissue regeneration remain controversial. Bone marrow from DsRed-transgenic donors was transplanted into recipients to lineage-trace circulating cells after myocardial infarction (MI). SDF was delivered post-MI, and hearts were evaluated for recruitment and plasticity of bone marrow-derived populations...

PURPOSE: In patients with left-sided HF, there has been less emphasis on the pathophysiology of the RV in terms of diagnostic evaluation and treatment, versus focus on structural abnormalities of the LV. This review seeks to delineate the importance of RV dysfunction in terms of its contribution to symptomatic limitations and cardiovascular outcomes in patients with left-sided HF. RECENT FINDINGS: Recent studies have demonstrated that RV dysfunction is common in both HFpEF and HFrEF, but more pronounced in HFrEF...

Heart transplantation (HTx) is considered an efficient and gold-standard procedure for patients with end-stage heart failure. After surgery, patients have lower aerobic power (VO2max) and compensatory hemodynamic responses. The aim of the present study was to assess through a systematic review with meta-analysis whether high-intensity interval training (HIIT) can provide benefits for those parameters. This is a systematic review with meta-analysis, which searched the databases and data portals PubMed, Web of Science, Scopus, Science Direct and Wiley until December 2016 (pairs)...

INTRODUCTION The N terminal prohormone of brain natriuretic peptide (NT proBNP) is secreted by cardiomyocytes in response to increased wall stress resulting from pressure and volume overload. The modified Model for End Stage Liver Disease (modMELD) scale reflects the systemic effect of heart failure (HF), which includes end-organ congestion and subsequent hepatic and renal dysfunction. OBJECTIVES The aim of this study was to assess the prognostic accuracy of NT proBNP and the modMELD score, as well as to compare their usefulness in the risk stratification of patients with end-stage HF awaiting orthotopic heart transplantation (OHT)...

Treatment of advanced heart failure with implantable LVADs is increasing, driven by profound unmet patient need despite potential serious complications: bleeding, infection, and thrombus. The experimental objective was to develop a sensitive imaging approach to assess early thrombus accumulation in LVADs under operational high flow and high shear rates. Methods : A monomeric bifunctional ligand with a fibrin-specific peptide, a short spacer, and99m Tc chelating amino acid sequence (F1A) was developed and compared to its tetrameric PEG analogue (F4A)...

OBJECTIVES: Myocardial infarction (MI) causes significant loss of cardiomyocytes, myocardial tissue damage, and impairment of myocardial function. The inability of cardiomyocytes to proliferate prevents the heart from self-regeneration. The treatment for advanced heart failure following an MI is heart transplantation despite the limited availability of the organs. Thus, stem-cell-based cardiac therapies could ultimately prevent heart failure by repairing injured myocardium that reverses cardiomyocyte loss...

There is little data outlining the use of outpatient inotropic medications in patients with existing left ventricular assist devices (LVADs). This case series explores this patient population and seeks to define the indications, complications, and safety of dual support. A retrospective chart review was conducted for all patients on LVAD and then subsequently started on home inotropes post device implant. Eight patients met inclusion criteria. The indications for inotropes were right ventricular failure, aortic insufficiency with biventricular failure, LVAD thrombosis with contraindication to device exchange, and cannula malposition with elevated pulmonary vascular resistance...

Background -Heart failure (HF) survival has improved and nowadays many patients with HF die from non-cardiac causes, including cancer. Our aim was to investigate whether a causal relationship exists between HF and the development of cancer. Methods -HF was induced by inflicting large anterior myocardial infarction (MI) in APCmin mice, which are prone to develop precancerous intestinal tumors, and tumor growth was measured. In addition, to rule out hemodynamic impairment, a heterotopic heart transplantation model was employed, where an infarcted or sham-operated heart was transplanted into a recipient mouse, while the native heart was left in situ...

We describe a male patient who presents 2 years posttransplant with cough and dyspnea. A negative pulmonary workup led to an endomyocardial biopsy and the diagnosis of cytomegalovirus (CMV) myocarditis. The patient was treated with ganciclovir and intravenous immunoglobulin. This illustrates a very late presentation of posttransplant CMV myocarditis and the usefulness of myocardial biopsy in diagnosis of CMV carditis.

We report a case of successful combined heart liver transplant in a patient with a congenital solitary kidney. The patient had normal renal function before combined heart-liver transplantation and developed acute kidney injury requiring slow continuous dialysis and subsequent intermittent dialysis for almost 8 weeks post transplantation. Her renal function recovered and she remains off dialysis now 7 months post transplantation. She only currently has mild chronic renal insufficiency. We believe this is the first reported case of successful heart liver transplant in a patient with a congenital solitary kidney...

Children with single ventricle physiology have complete mixing of the pulmonary and systemic circulations, requiring staged procedures to achieve a separation of these circulations, or Fontan circulation. The single ventricle physiology significantly increases the risk of mortality in children undergoing non-cardiac surgery. As liver transplantation for patients with single ventricle physiology is particularly challenging, only a few reports have been published. We herein report a case of successful LDLTx for an 8-month-old pediatric patient with biliary atresia, heterotaxy, and complex heart disease of single ventricle physiology...
